Abstract

A process for purifying a naphthalenic carboxylic acid comprising contacting at a temperature below about 575° F. a mixture comprising an impure naphthalenic carboxylic acid and a solvent in the presence of hydrogen gas with a noble metal on carbon catalyst. The process results in reduced amounts of organic impurities in the purified acid when compared to other purification processes.
